I’m not sure I can post this question here. However, it’s related to Matchmaking. So I hope I’m not posting in the wrong place.
I’m figuring out how SNS Topic for Matchmaking works and how I set up it for Matchmaking. I followed “Set up FlexMatch Event Notification”. But I have no idea where I can get messages from the SNS Topic and I don’t know whether I exactly set up the SNS Topic. Now I’m using Polling through DescribeMatchmaking() on Lambda to track status of a ticket id. However, I prefer using SNS Topic rather than using Polling because the SNS Topic is more efficient.
Any hints are appreciated.
